采用实测方法,对北京市83台住宅空调机的待机功率进行测试,并对住户空调待机行为进行调查,由此计算出北京市和全国城镇住宅空调的待机能耗。结果表明:单台分体空调机待机功率为1.0W～4.6W,平均值为1.67W。节能空调机的平均待机功率高于普通空调机。49.4%的住宅分体空调机在非空调季仍处于通电待机状态。调查对象的空调待机能耗约为夏季空调运行能耗的13%。2010年北京市和全国城镇住宅空调待机能耗分别为0.58亿度和22.5亿度,住宅空调待机行为节能潜力很大。
The test method was used to test the standby power of 83 residential air conditioners in Beijing and to investigate the standby behavior of residential air conditioners. The standby energy consumption of urban residential air conditioners in Beijing and the whole country was calculated. The results show that the standby power of single split air conditioners is 1.0W ~ 4.6W with an average value of 1.67W. The average standby power of energy-saving air conditioners is higher than ordinary air conditioners. 49.4% of the residential split air conditioner in the non-air conditioning season is still in power standby. The air-conditioned standby energy consumption of the respondents was about 13% of the energy consumption of summer air-conditioners. In 2010, the stand-by energy consumption of air-conditioners for urban residential buildings in Beijing and the whole country were respectively 0.58 billion kWh and 2.25 billion kWh, and the potential for standby energy saving in residential air-conditioners was high.
